SCRAPER.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed pril 14:, 1906. Serial No. 311,791.

To all whom it may concern:

Be it known that I, LEwrs E. WATERMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Scrapers, of which the following is a specification.

The object of this invention is to construct a scraper for disk plows which is supported in a manner to enable it to do the best work under varying conditions.

In the accompanying drawings, Figure 1 is a face representation of a disk of a disk plow to which is applied my improved scraper. Fig. 2 is an edge elevation of the scraper and its support. Fig. 3 is a vertical section on dotted line a a, Fig. 1.

The disk 1 is of an ordinary construction, to which is connected a scraper-support 2. This support has a rectangular opening in its upper portion 3. A rectangular bar is composed of the two sections 4 and 5, located at substantially right angles to each other. The section 5 of the rectangular bar is located in the opening in the scraper-support 2 and is held in place therein by the set-screw 6/ A scraper 7 is constructed from sheet material and is curved so that its lower edge will fit the concavity of the plowing-disk 1. To the rear face of the scraper is secured a plate 8, having its upper end provided with a curved slot 9. A standard 10, cylindrical in cross-section, is connected to the section 4 of the rectangular bar by the clamp in two parts 11 and 12 and a U-bolt 13, embracing standard and connecting the sections 11 and 12. This clamp is bodily movable in the lengthwise direction of the section 4 and can be clamped in its adjustable position by means of the nuts 14. The standard can be raised and lowered and clamped when adjusted. The lower end 15 of this standard is in a segment of a circle. An intermediate section 17 has its lower end pivotally connected to the plate 8 by the bolt 18. The upper end of this intermediate section has a concave surface 19, within which is received the curved lower end of the standard. A bolt 20 passes through the slotted lower end of the standard 10, through the upper end of the intermediate section 17, through the curved slot 9 of the plate 8, and receives a nut 21 on its projecting end.

The curved slot 19 permits the scraperblade to be rocked on the bolt 18 as a center in order that the lower edge of the blade may stand horizontally or at an angle thereto. The curved surface of the lower end 15 of the standard 10, in connection with the curved surface 19, will permit the upper edge of the blade to be tipped away from the face of the plowing-disk more or less to suit the different conditions of soil. The blade and its stand ard-support can be raised or lowered bodily in order to permit the soil to be elevated. more or less before it encounters the scraper.

By the various adjustments the scraperblade can be presented, in connection with the plowing-disk, in the proper position to do the best work when the condition of the soil is considered.

I claim as my invention A scraper for disk plows comprising a standard-support having its lower end curved, a blade, a plate secured to the rear face of the blade, the plate provided with a curved slot, an intermediate section having a pivotal connection with the plate, and an engagement with the curved lower end of the standard, and a bolt which connects the curved surfaces andpasses through the curved slot of the plate.
